Specification of Letters Patent.

Patented Dec. 15, 1914.

Application filed June 4, 1914. Serial No. 842,937.

To all whom it may concern.

Be it known that I, FRED BAsnnow, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented *a certain new and useful Improvementin F lash- Lamp Attachments for Electric Batteries; and 1 do hereby declare that the following description of my said invention, taken in connection with the accompanying sheet of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates generally to improvements in a flash lamp attachment for electric batteries and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter llrst fully set forth and described and then pointed out in the claims.

In the sheet of drawings already referred to, which serves to illustrate more fullyniy said invention, Figure 1 is a longitudinal, vertical section of my device. Fig. 2 is a section in line 22 of Fig. 1. Fig. '8 is a longitudinal, vertical section on an enlarged scale of a fragment thereof. F ig. 4 isalike section disclosing a slight modification of construction. Fig. 5 is a vertical section through a detail of my flash lamp. Fig. 6 is an elevation of afragment showingthe invention as applied to a cylindrical dry cell or battery. Fig. 7 is a plan section thereof in line 77 of Fig. 6.

Like parts are indicated by corresponding symbols or characters of reference in all the figures of the drawings;

The object of my invention is the provision of asimple, handy, and eificient attachment which may be applied to any; of the many standard electric batteries or dry cells now on the market, whereby the'latte r may, without change or niodific'lation, be converted into serviceable flash a for any purpose whatever. And. correlated therewith, said invention conte' plates means for oscillating .the ,lamp portion thereof to any angle desired with respect to the said battery so that light may be directed to obscure and inaccessible corners impossible toreach were the lamp or bulb fixedly attached to the source of electric energy. I s In the drawing 10 indicates a typical type of rectangular dry cell and 11 the carbon element projecting exteriorly there of. This element has a horizontally extending binding post 13 and nut 14 for attachment of connections, and the zinc eleinent of said cell has an upstanding binding post and nut l2 and 12 respectively. This construction istypical of a standard cell and in lighting attachment therefor comprises irst an angular sheet metallic member 15,=tl1e horizontal leg 1 5 01 which is punctured for the reception of a tubular flanged insulating member 16, which member is adapted to embrace the binding post 12, the nut 12*"- of which is intended t -bear upon the flange of saidinsulation there being a strip of insulating material 17 interposed between said horizontal leg 15 of angular member 15 and the top of battery 10, so that the said member is thoroughly insulated from the binding post 12.

Angular member 15 is so fixed to binding post 12 that its vertical leg 15 is disposed in a plane parallel to the plane ofthe carbon element 11, and said legis punctured in alinement with binding post 13 for the reception of a bolt 18 over Which is pivoted a leg 19 of an inverted U-shaped niember 20, alike leg 21 of said member being similarly pivoted over said binding post 13 of the carbon element 11. The horizontal extensions 22 and 23 of U-shaped member 20 overlap, but are insulated from each other by a strip of insulating material 24, and, surmounting said horizontal eXtcnsions,- is an internally threaded shell or socket 25 \yhich is fixedto and in electrical contact with-the horizontal extension 22 but insulated from extension 23 by insulation 26- as clearly seen in Figs. 3 and 4. Adapted to be threaded into socket 25 is an incandescent lamp or bulb 27, the contact 28 of which forms an electrical connection with horizontal extension 23 through an aperture 29 in insulation 26. It is to be understood that the exteriorly threaded shank 30 orms electrical. contact with interiorly threaded shell 25. Fixed to vertical leg 15 of angular member 15 is a blade 31 of springy sheet metallic material, which blade when depressed by'the finger of a hand forms electrical contact with binding post 12, thereby closing an electrical circuit and illuminating bulb 27. Fixed to the upper end. of interiorly threaded shell or socket 25 is a reflector 32, which reflector is provided with a bead 33 at its open end for the reception of a lens 34, a split wire ring 35 being snapped into said head to retain the lens in position and to permit the removal thereof.

In Fig. 5 I disclose in detail a construction of the reflector which may be employed in many instances. Within the reflector shell 32 is located a frosted glass reflector 32 which, with the lens 34, is maintained in position by wire 35 located in the bead 33 as hereinbefore described.

In Fig. 4 is indicated a slight modification of the switch for closing the electrical circuit. In this construction leg 21 is pivoted on binding post 13 as before, but is insulated therefrom by insulation 40. An aperture 41 is formed in carbon element 11 for the passage therethrough of a stud 42 fixed to a spring member 43 attached to the carbon element 11. By pressing inwardly on said spring member 43 said stud contacts with leg 21, thereby forming electrical contact in a manner readily understood.

In Figs. 6 and 7 1 illustrate another modification in the arrangement of the switch. A strip of insulating material 50 is fastened to binding post 12 and the horizontal leg 15 is fixed to said insulating material. thumb nut 51 coacts with binding post 12. A sheet metallic spring blade 52 is pivotally mounted on insulating strip 50 by a rivet 53, which rivet is in electrical connection with leg 15*. One face of the blade 52 is formed with a cut out 54, adapted to partially embrace thumb nut 51, to close the circuit and it is evident that when the blade 52 is oscillated away from said thumb nut, said circuit is open.

While it is intended that my invention bemarketed independently of the batteries, yet in a more elaborate contemplation, I may supply the battery as well, and with the same a suitable open topped battery gasizig A having a bail B and a fixed han- While herein I have disclosed the preferred mode of practicing my invention and also several modifications thereof, 1 wish it understood that I may make such other changes and alterations as would suggest themselves to the skilled mechanic or permitted under the doctrine of equivalents.

Having thus fully described my invention I claim as new and desire to secure to myself by Letters Patent of the United States I 1.
